Yellowstone Caldera Coffee Mugs
The Yellowstone Caldera is a 43-mile-by-28-mile supervolcano located in the northwest corner of Wyoming in Yellowstone National Park. It was formed during the last of three supereruptions that have taken place over the last 2.1 million years, known as the Lava Creek eruption, which occurred approximately 640,000 years ago. For big fans of this natural geographic wonder, you can enjoy your morning Joe in one of our Yellowstone Caldera coffee mugs.
